I didn't take the final originally because I had a 105ºF fever. Many complications have since passed, and I guess the teacher judged that based on my numerous attempts at trying to retake the test alongside my high grades and obvious comprehension of the class, I deserved an A.
Math and science are the two things that I have never had a problem understanding; if she didn't give me the A then, I would have received it after taking the exam.
Using this logic, I wouldn't even need a bribe, because I'm just that damn good.
